DETAILED DESCRIPTION OF THE INVENTION
In the following, an embodiment of the present invention will be described with reference to FIGS.
In FIG. 1, reference numeral 20 denotes a positioning device according to the present embodiment. The positioning device 20 is mounted on a base 24 on which a panel 22 is placed and a pair of adjacent panels 22 mounted on the base 24. A plurality of positioning means 26 with which the sides 2202 and 2204 are brought into contact with each other, and the positioning means 26 are arranged so as to face each other. And pressing means 28 for contacting the positioning means 26.
Each positioning means 26 includes an abutting block 30 whose posture can be changed at a predetermined angle around an axis perpendicular to the base 24, a fixed block 32 for fixing the abutting block 30 to each posture changing position, and the abutting The block 30 is provided with a plurality of abutting pins 34 projecting along a plane parallel to the base 24 and with which the panel 22 is brought into contact.

More specifically, the base 24 is formed with a rectangular window 2402 for processing the panel 22 and is formed in a frame shape as a whole, and a pair of adjacent sides 2404 and 2406 adjacent thereto. Above, the positioning means 26 is provided.
[0015]
Of these pair of sides 2404 and 2406, one of these positioning means 26 abuts on one side 2404 and two on the other side 2406 at a predetermined interval in the length direction of this side 2406. Each is provided via a plate 36.
Further, in this embodiment, the abutting block 30 constituting the positioning means 26 is formed in a square shape in plan view as described in detail in FIG. 2, and the abutting block 30 is located at the upper diagonal position. Protrusions 3002 and 3004 to which the pins 34 are attached project, a long abutting pin 3402 is attached to one protrusion 3002, and a short abutting pin 3404 is attached to the other protrusion 3004.
[0016]
The abutting pins 3402 and 3404 are attached to the abutting block 30 by being screwed to the protrusions 3002 and 3004 via screw portions 3406 and 3408 formed at the base end portions thereof. In addition, the fixing nut 38 screwed to the screw portions 3406 and 3408 is fixed to the protrusions 3002 and 3004 by being brought into contact with the protrusions 3002 and 3004.
The abutting pins 3402 and 3404 are spaced apart from each other by a distance of 180 degrees around the axis perpendicular to the base 24 in the opposite direction from the abutting block 30, that is, at the 24 bases where the abutting block 30 is placed. It is made to protrude.
[0017]
Further, by rotating the abutting pins 3402 and 3404 around the axis, the protruding lengths of the abutting pins 3402 and 3404 from the abutting block 30 can be changed. The screw portions 3406 and 3408 constitute a position adjusting mechanism.
Furthermore, a spherical resin contact 40 made of hard resin is attached to the protruding end of each of the butting pins 3402 and 3404.
[0018]
In the present embodiment, the fixed block 32 is formed in an L shape so as to be brought into contact with two side surfaces of the corner portion of the abutting block 30, and as shown in FIG. Three are provided corresponding to the three corners of the abutting block 30 and are fixed integrally on the abutting plate 36.
Therefore, the abutment block 30 is inserted between the fixed blocks 32 from above, so that the movement in the surface direction of the base 24 is restricted, and the relative movement around the axis perpendicular to the base 24 is performed. Be bound.
The abutment block 30 can be inserted and fixed between the fixed blocks 32 at a position rotated 180 degrees around the axis.

The fixed block 32 is formed with a through-hole 3202 that matches the locking hole 3006 when the fixed block 30 is inserted.
A retaining pin 42 for preventing the abutment block 30 from being detached from the fixed block 32 is inserted into the through hole 3202 and the locking hole 3006. The retaining member 3006 and the retaining pin 42 constitute the retaining means in the present embodiment.
[0020]
Next, the operation of the positioning device 20 of the present embodiment configured as described above will be described.
First, to fix the large panel 22, as shown in FIG. 1, in each positioning means 26, the abutting block 30 is placed between the fixing blocks 32 so that the short abutting pins 34 face the inside of the base body 24. After the insertion, the stopper block 42 is fixed to the base 22 by fitting the retaining pin 42 into the through hole 3202 and the locking hole 3006.
In this state, each abutment block 30 is restrained from relative movement in any of the surface direction and the direction orthogonal thereto with respect to the base body 22.
[0021]
Thus, after inserting the panel 22 between the positioning means 26 and the pressing means 28, the panel 22 is brought into contact with the positioning means 26 by operating the pressing means 28. The panel 22 is positioned.
[0022]
When switching to a smaller panel 22, after removing the retaining pin 42, the abutting block 30 is extracted upward and the long abutting pin 34 faces the inside of the base 24 again. Insert into the fixing block 32 and reattach the retaining pin 42.
As a result, the contact position between the positioning means 26 and the panel 22 is changed to the inside of the base 24 and the height from the base 24 is changed.
Thus, the panel 22 is positioned by operating the pressing means 28 to bring the panel 22 into contact with the positioning means 26.
[0023]
As described above, according to the positioning device 20 according to the present embodiment, the panel 22 can be removed by a simple operation in which the abutting block 30 is pulled out of the fixed block 32 and rotated by a predetermined angle and then inserted into the fixed block 32 again. The positioning position is changed.
Therefore, the setup work accompanying the change of the panel 22 is simplified, and the work time is greatly shortened.
[0024]
Further, in this embodiment, the retaining pin 42 reliably prevents the abutment block 30 from being detached from the fixed block 32, and also from this point, the displacement of the positioning position of the panel 22 is prevented.
Further, since the abutting pin 34 is screwed to the abutting block 30 via the screw portions 3406 and 3408, the protruding amount can be finely adjusted by the rotation operation of the abutting pin 34.
Therefore, fine adjustment of the positioning position of the panel 22 is possible, and high-precision positioning is possible.
[0025]
Note that the shapes, dimensions, and the like of the constituent members shown in the embodiment are examples, and can be variously changed based on design requirements and the like.
For example, in the above-described embodiment, the abutting block 30 has a square shape, and its three corners are abutted and supported by the fixed block 32, and the abutting pin is formed from two parallel sides of the abutting block 30. 34 is configured to project two types of panels 22 by projecting, but by changing the shape of the abutment block 30 to a polygonal shape, the posture change angle is reduced, In addition, by providing the abutting pins 34 on the side surface of the abutting block 30 at the same pitch as the posture change angle, it is possible to cope with three or more types of panels 22.
[0026]
